I had a great stay in Ploy's apartment. It is small (think small hotel sized room) but it's nearly new and has everything you might need. There's good wifi and cable tv has a range of mainly thai language channels. Pool is lovely too.
Location is either great or not so good depending on what you are looking for. It's in a pleasant and busy street with plenty of convenience stores. Not many restaurants as such close by but there's a great local food market with various stalls selling local foods and has ample seating. The local grilled fish straight from the charcoal grill is particularly delicious. Its about 10 mins walk to the nearest subway station and also a large modern shopping mall which has a wide range of eateries inside.
It's also very close (25 mins walk or 1 subway station trip) to the world famous Chatuchak weekend markets.
The street is busy and lots of people are out and about even late at night, so it is very safe at all hours walking to and from the subway.
A couple of potential negatives (again these depend on your individual wishes and needs).
Although the street is busy and the building is easy for taxi's to find to drop you off there not many empty taxi's drive along it. So waiting for a taxi to come along is a very hit and miss affair. You might be waiting a while is all I'm saying. If you don't have heavy bags then you can walk the 10 mins to the main road or subway station and heaps of taxi's are available there.
The only other thing to note is that there is no hot water. This is not uncommon in Bangkok but unusual for a relatively new building. Given that it is damn hot most days then having a cold/cool shower might not bother you. But for cold weather dwelling farangs like myself you might still prefer a warm if not hot shower. Anyway just something to be aware of. The lack of hot water in the shower is really the only negative I personally would comment on.
Ploy is an extremely helpful and accommodating host and checkin and checkout were very smooth and hassle free.
Highly recommended.
